I recently started with a fresh Nauvis map again, and this is easily my most ambitious Factorio effort yet. Determined to clear out all of the bugs inside the walls! This is still one of the most fun ways to play Factorio. I'd encourage you to drop in on the Reddit Factorio forum and remind people this map is out here. It's truly incredible and I still like running across all of the hidden goodies and filling in each example of "what the heck happened here!?" Thanks again!
